Photochemical Enhancement of Combustion and Mixing in Supersonic Flows,

Abstract

Initiation and combustion enhancement of gaseous (vaporized or atomized) fuel-air mixtures can be produced photochemically by ultra-violet irradiation in both stationary and flowing mixtures. Induced combustion characteristics are different from normal thermal ignition (e.g., spark plug), and provide for ignition and enhanced combustion at conditions where thermal ignition is impossible. The potential for practical application of photochemically induced effects in chemical energy conversion devices (e.g., aircraft gas turbines, ramjets) is further facilitated by the availability of higher efficiency light sources. The designer is thus provided with a novel and practical method of combustion initiation and enhancement which departs from the usual thermal method. (Author)
